North Korea has supplied weapons to Syria and Myanmar, according to a confidential report by independent United Nations monitors which also said Pyongyang violated UN sanctions to earn nearly $200m in 2017.

The report to a UN security council sanctions committee, seen by Reuters on Friday, said monitors had investigated ongoing ballistic missile cooperation between Syria and Myanmar, including more than 40 previously unreported North Korea shipments between 2012 and 2017 to Syria’s Scientific Studies and Research Centre, which oversees the country’s chemical weapons programme.
